How to Read the Prices on Txdot

The Texas Section of Transportation this week unveiled its latest proposals to widen the busiest stretch of highway in Central Texas to more than 20 lanes in some areas, significantly increasing Interstate 35'south capacity for traffic while engulfing side by side property. The state agency is soliciting public input for the next month.
The $four.9 billion plans — which include calculation two non-tolled lanes in each direction, building straight connectors at I-35 and US 290 East, lowering the main lanes and eliminating the upper decks — have already drawn criticism from community groups that have advanced competing proposals to reduce I-35'southward footprint.
But TxDOT is not a huge fan of their ideas, either.
The plans the groups submitted to TxDOT were largely dismissed past the agency's academic partners at the Texas A&Thou Transportation Constitute as being either bad for drivers or prohibitively expensive.
The first and arguably about dramatic proposal calls for shrinking the interstate to a transit-heavy urban boulevard.
Rethink35'south concept imagines turning the highway into a 6-lane road that would include dedicated charabanc lanes, parks, protected wheel paths and broad sidewalks. The boulevard would exist flanked by mixed-use buildings hosting restaurants and retail stores at the ground level with housing options higher up, some of which would be affordable homes offered to displaced households.
In short, I-35 would be transformed into the blazon of densely populated, pedestrian-friendly urban environment typical of many East Coast cities.
Rethink35'due south vision reflects a growing motility in the United States to remove highways that tore through neighborhoods decades agone, disproportionately displacing people of color and stamping out ground-level community civilities.
TTI argued ReThink35'south proposal would push traffic congestion, including freight trucks, to neighborhood streets and other Austin highways, increasing commuters' travel times and compelling them to either move closer to their jobs or find employment inside a reasonable distance from their homes.
Rethink35 said TTI's review of the proposal was scant.
"TTI'south study was anemic from the kickoff. They were given hardly any fourth dimension to a serious analysis of the community alternatives," said Adam Greenfield, co-founder of Rethink35. "I think it should basically ignored."
A 2d proposal from another community group calls for putting I-35 underground in the urban cadre and having the newly reclaimed ground-level space serve every bit a boulevard lined with affordable housing, green spaces, offices and stores. Reconnect Austin says the plan would create more than 136 acres of new developable state, increasing the city's tax base of operations by billions of dollars.

The TTI analysis said many parts of the Reconnect Austin programme would meet TxDOT'due south highway chapters goals, just the Institute found that lowering I-35 and putting a lid on tiptop "may be prohibitively expensive." TTI estimated the cost of such a covering from Cesar Chavez Street to MLK, Jr. Boulevard at shut to $500 meg. TxDOT could not pay for that, so the tab would have to be picked up by a third party.
Reconnect Austin said TTI failed to consider the additional acquirement that its proposal would generate.
"I retrieve there's some holes in the logic," Reconnect Austin co-founder Hayden Black Walker said. "Country in downtown Austin is incredibly valuable. If y'all narrow the footprint and utilise the land in a different style, y'all could really have revenue to kickoff the cost, but TxDOT has never considered that."
The third customs proposal analyzed by TTI would lower I-35 in the downtown area and push the frontage roads inwards to hang over the main lanes, thereby reducing the space occupied past the interstate.
The plan from the Downtown Austin Alliance and the Urban Country Institute calls for adding "caps" (large decks covering the main lanes that would run north to s) and "stitches" (widened bridges running east to west over the highway). Proponents point to Klyde Warren Park in Dallas or the Cap at Union Station in Columbus, Ohio.

The TTI analysis was most amenable to the DAA/ULI vision, proverb information technology was closest to the TxDOT proposals. But some of TTI's biggest concerns with the proposal included the engineering difficulty of routing on-ramps from overhanging frontage roads on to the chief lanes without running into caps. TTI estimated the caps and stitches would toll betwixt $198 one thousand thousand and $225 1000000, with maintenance and operations costs of effectually $2 million per twelvemonth. TxDOT would not pay for the price of covering I-35.
"I retrieve there'south a big amount of work to exist done to place funding for that," Downtown Austin Alliance Vice President of Planning Melissa Barry said. "The [Biden] administration is prioritizing that type of piece of work. We retrieve there will be more funding available in the future, and then we're optimistic."
The public has until Sept. 8 to weigh in on TxDOT's plans, which call for construction to first in late 2025. And while the country agency says it's open to modifying its proposals for the interstate, TxDOT won't start over from scratch.
"We are nonetheless moving forward," TxDOT spokesperson Diann Hodges said. "In that location are withal things that we can tweak about this, and then nosotros want to hear from the community to make certain we are getting this project right."
